Technical problem to be solved in the utility model be exactly provide at the present situation of above-mentioned prior art a kind of have structural strength and operating accuracy preferably, low, the corrosion resistant pump-foot of cost.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: a kind of pump-foot, this base is provided with screw and the base mounting hole that the fixedly pump housing and motor are used, it is characterized in that: described base adopts polyester resin, glass fiber compound material, be provided with stiffening rib in this base, adopt compression molding to make integrative-structure.
Adopt composite material to make and to obtain resistance to compression preferably, antivibration and shear-stable mechanical property and operating accuracy.
The utility model is to solve the problems of the technologies described above another technological scheme that is adopted to be: die press technology for forming is made in the die cavity of described composite material base employing moulding.Adopt the moulding pressing moulding process can improve its structural strength and rigidity; Thereby can further improve the operating accuracy and the working life of pump.
Described screw can be set to metal nuts, and this metal nuts is embedded in the shaping mold cavity of described base in advance, and with this base compression molding one.
Described stiffening rib can be set to metal reinforcing, and this metal reinforcing is embedded in the shaping mold cavity of described base in advance, and is integral with this base compression molding.
Described base mounting hole can be set to metal bolts hole ear, and this metal bolts hole ear is welded on the described metal reinforcing, and is embedded in advance in the shaping mold cavity of described base jointly, and is integral with this base compression molding.
The metal reinforcing that described metal reinforcing can be set to the housing metal reinforcing and arrange in length and breadth, this housing metal reinforcing and the metal reinforcing integral solder of arranging in length and breadth form; Its effect is to improve its whole structural strength and rigidity.
Described metal reinforcing preferably adopts knotted bar iron to make; Help improving and base that composite material is made between adhesive strength.
Compared with prior art, the utility model is owing to adopt the pump housing base of polyester resin glass fiber composite material by die forming, comprise also that wherein Framework Of Steel Reinforcement with abilities such as the resistance to compression that strengthens base and anti-shearing, antivibratioves, also comprises the internal fixation screw of motor and pump housing joint.This base has solved the problem that the available technology adopting iron member exists effectively, eliminated cast iron base and produced corrosion phenomena because of corrosion, increased its working life greatly, simultaneously since the characteristic of composite material effectively buffering vibration, reduce noise, use the mold pressing manufacturing because of it again, size is unified, surfacing.Therefore need not processing paint and just can directly assemble use.Simultaneously manufacturing is compared its cost of production and can be descended 60% with cast iron.Also have certain insulating property, Security is good.The utility model has reached the practical application purpose of anti-corrosive pump base by the change of material property optimization and structure.
Description of drawings
Fig. 1 is the structural representation of the utility model base;
Fig. 2 is an embedded nut structural representation of the present utility model;
Fig. 3 is housing metal reinforcing of the present utility model, the metal reinforcing of arranging in length and breadth and the integral solder structural representation of metal bolts hole ear;
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 and Fig. 3 show a mode of execution of a kind of pump-foot of the utility model, are provided with by housing metal reinforcing 51 in this base 10 and stiffening rib 5 that the metal reinforcing of arranging in length and breadth 52,53 is formed, and as shown in Figure 3, this stiffening rib is made of knotted bar iron.
In order to make the pump housing and motor be convenient on base, install, when the base plate die forming, adopt the embedded nut mode, metal nuts is placed die cavity, by mold pressing nut and base being fixed together becomes embedding nut 2.Thereby be provided with the embedded with metal nut 2 of being with screw 4 the limit week of this base, and base mounting hole 3, as shown in Figure 1, 2.
Die press technology for forming is made in the die cavity of described base 10 employing polyester resin, glass fiber compound material making and employing moulding.
This embedded with metal nut 2 is embedded in the shaping mold cavity of base in advance, and is integral with this base compression molding.
Stiffening rib 5 also is to be embedded in advance in the shaping mold cavity of base, is integral with this base compression molding.
The utility model pump-foot is the overall thermal compression molding, by increasing stiffening rib 52,53 in length and breadth, adopts pre-buried mode, places shaping mold cavity, by mold pressing and composite material strong bonded, to reach maximum resistance to compression, anti-shear ability.
Fix for the ease of whole machine installation, in the fabricating yard, be fixed with the installation screw; Be welded with bolt hole ear 6 again on stiffening rib 5, it is corresponding with the position of bolt hole ear 6 that this installs screw; This bolt hole ear 6 places die cavity and by mold pressing and composite material strong bonded.
The utility model is simple in structure, and it is convenient to be shaped, and need not deep processing after the shaping, is effectively to solve anti-corrosive pump base corrosion and energy saving easily, a kind of effective measures that reduce production costs.
